Visual playlist

ABSTRACT

A device may receive information that identifies a first attribute and a second attribute associated with media files, and the first and second attributes may specify a manner in which the media files are to be represented on a user interface. The device may present, on the user interface and based on the first attribute and the second attribute, a representation of the media files on a grid. A first dimension of the grid may be associated with the first attribute, and a second dimension on the grid may be associated with the second attribute. The device may receive a selection of a portion of the grid corresponding to a set of media files, and may create a playlist, based on receiving the selection, that includes the set of media files.

BACKGROUND

A music listener may use a device, such as a media player, to create aplaylist of songs. A playlist may include a list of songs that can beplayed in sequential or shuffled (e.g., random) order. A music listenermay create and store a playlist so that a series of desired songs (e.g.,songs that create a particular musical atmosphere, songs of a particularstyle or a variety of styles, etc.) can be played without requiringcontinued user interaction.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following detailed description of example implementations refers tothe accompanying drawings. The same reference numbers in differentdrawings may identify the same or similar elements.

As used herein, the terms “content” and “file” or “files” may be usedinterchangeably. In some implementations, a file may store and/oridentify content. For example, a media file may store media content, anaudio file may store audio content (e.g., a song), and a video file maystore video content. Media content may include audio content and/orvideo content.

A music listener may use a user device, such as a media player, tocreate a playlist of songs. However, creating a playlist may betime-intensive as a user navigates through various folders and files toadd songs to the playlist. Implementations described herein simplify theplaylist creation process by allowing a user to create a playlist byselecting a representation of a song or a group of songs presented(e.g., displayed and/or provided) on a two-dimensional grid thatcategorizes songs based on a pair of attributes.

FIG. 1 is a diagram of an overview of an example implementation 100described herein. As illustrated in FIG. 1, a user may interact with auser device, such as a smart phone or a media player, to create aplaylist. As shown in box 110, a song may be represented on atwo-dimensional grid presented on a user interface, and a position ofthe song on the grid (e.g., a cell that represents the song) may bebased on attributes of the song. A position on the grid (e.g., a cell)may correspond to a single song or a group of songs with particularattributes.

In implementation 100, the vertical axis of the grid represents a tempoof a song (e.g., a number of beats per minute), and a song may berepresented at a position on the grid based on the tempo of the song.For example, a song with a fast tempo may be represented closer to thetop of the grid than a song with a slow tempo. Likewise, a song with aslow tempo may be represented closer to the bottom of the grid than asong with a fast tempo.

In implementation 100, the horizontal axis of the grid represents agenre of a song (e.g., classical, dance, rock, pop, rap, top 20, etc.),and a song may be represented at a position on the grid based on thegenre of the song. For example, a classical song may be representedcloser to the left of the grid, and a dance song may be representedcloser to the right of the grid.

As shown in box 120, a user may select one or more cells on the grid.For example, a user may use their finger on a touch screen interface toselect one or more cells on the grid, as illustrated. Each cell selectedby the user may represent one or more songs, and the represented songsmay be added to a playlist, as shown in box 130. The user device mayplay the songs in the playlist.

The number of components shown in FIG. 3 is provided for explanatorypurposes. In practice, device 300 may include additional components,fewer components, different components, or differently arrangedcomponents than those shown in FIG. 3. Additionally, or alternatively,each of user device 210 and/or server device 220 may include one or moredevices 300 and/or one or more components of device 300.

FIG. 4 is a flow chart of an example process 400 for creating aplaylist. In some implementations, one or more process blocks of FIG. 4may be performed by user device 210. Additionally, or alternatively, oneor more process blocks of FIG. 4 may be performed by another device or agroup of devices separate from or including user device 210, such asserver device 220.

As shown in FIG. 4, process 400 may include receiving a request todisplay a representation of media files (block 410). In someimplementations, user device 210 may receive the request from a user ofuser device 210 interacting with a user interface of user device 210.For example, a user may select an application (e.g., a Visual Playlistapplication, a media application, a playlist-creation application,etc.), which may initiate the request. In some implementations, themedia files may be stored on user device 210 and/or server device 220.

Process 400 may include receiving information that identifies a firstattribute and a second attribute that specify a manner in which themedia files are to be represented on a user interface (block 420). Insome implementations, user device 210 may receive the information from auser of user device 210 interacting with a user interface of user device210. For example, a user may specify a first attribute to be representedalong a first axis (e.g., a vertical axis, or y-axis), and may specify asecond attribute to be represented along a second axis (e.g., ahorizontal axis, or x-axis). User device 210 may present a grid on auser interface, with each cell and/or position on the grid correspondingto a first position (e.g., a y coordinate) along the first axis and asecond position (e.g., an x coordinate) along the second axis. Thepositions along the axes may correspond to respective attribute values.Each cell on the grid may represent one or more media files having afirst attribute value corresponding to the first position along thefirst axis, and having a second attribute value corresponding to thesecond position along the second axis.

The first and second attributes may identify information associated witha media file (e.g., an audio file, such as a song; a video file, such asa music video of a song, a movie, or a television program; etc.). Forexample, the first or second attribute may identify a tempo of a song(e.g., a quantity of beats per minute), a genre of a song (e.g., rock,rap, country, pop, dance, classical, comedy, talk, etc.), a release dateof a song (e.g., a day, month, and/or year that the song was released),an artist associated with the song (e.g., a writer of the song, a singerof the song, a producer of the song, etc.), an album on which the songwas released, a name of the song, a length of the song (e.g., in minutesand/or seconds), a voice frequency associated with the song (e.g., ahigh pitched voice, a low pitched voice, a male voice, a female voice,etc.), a mood associated with the song (e.g., warlike, obscure, sad,serious, pious, furious, joyful, splendorous, bright, peaceful, light,soft, rich, gentle, melancholy, etc.), a rating of the song (e.g., auser rating), a quantity of times that a user has selected the song forplayback (e.g., a quantity of times user device 210 has played thesong), a date that the user acquired and/or purchased the song, a datethat the user last played the song, a country and/or geographic regionassociated with the song (e.g., a country of origin, a country of theartist of the song, etc.), a musical instrument type used in the song,and/or another attribute associated with the song and/or media file.

While the attributes are described above as being associated with songs,in some implementations, the attributes may be associated with adifferent type of media content, such as a video (e.g., a music video),a podcast, an audio recording other than a song, etc.

In some implementations, user device 210 may also receive informationthat identifies a granularity for an attribute, and the granularity mayalso specify a manner in which the media files are to be represented onthe user interface. The granularity may indicate a manner in which songrepresentations should be distributed into intervals along the axes. Forexample, a user may specify that tempo is to be presented along avertical axis, and may specify a granularity, for the tempo, of 20 beatsper minute (“bpm”). When presenting the representation of the songs,user device 210 may group songs along the vertical axis based on thespecified granularity of 20 bpm. For example, songs with a tempo of81-100 bpm may be represented at a first position along the verticalaxis (e.g., at a bottom position), songs with a tempo of 101-120 bpm maybe represented at a second position along the vertical axis (e.g.,higher than the first, bottom position), and songs with a tempo of121-140 bpm may be represented at a third position along the verticalaxis (e.g., higher than the second position).

When the attribute is genre, the granularity may specify a quantity ofgenres to group together. For example, when a user selects a granularityof two for a genre attribute, user device 210 may group two similargenres together (such as rap and hip-hop, rock and classic rock, danceand pop, etc.). Similarly, when the attribute is mood, the granularitymay specify a quantity of moods to group together. For example, when auser selects a granularity of three for a mood attribute, user device210 may group three similar moods together (such as light, soft, andpeaceful; sad, serious, and melancholy; joyful, bright, and splendorous,etc.). In some implementations, the user may categorize the songs intogenres and/or moods, and may specify the genres and/or moods to bepresented (and/or the order in which the genres and/or moods arepresented along the axes).

When the attribute is release date, the granularity may specify aquantity of years, months, etc. to group together. For example, when auser selects a granularity of 10 years for a release date attribute,user device 210 may group songs released in the same decade (e.g., songsreleased in the 1970s, 1980s, 1990s, etc.). Similarly, when theattribute is a date that the user acquired, purchased, or last playedthe song, the granularity may specify a quantity of years, months, etc.to group together. For example, when a user selects a granularity of 1month for an attribute of last playback of a song, user device 210 maygroup songs played in the past month, songs played between one and twomonths in the past, etc.

When the attribute is song length, the granularity may specify a lengthof a song in minutes and/or seconds. For example, when a user selects agranularity of 30 seconds for a song length attribute, user device 210may group songs with a length that falls into 30 second time intervals(e.g., songs between 3 minutes and 3 minutes 30 seconds in length, songsbetween 3 minutes 30 seconds and 4 minutes in length, etc.).

When the attribute is artist name, album name, or song name, thegranularity may specify a quantity of letters that start the artistname, album name, or song name. For example, when a user selects agranularity of two letters for an artist name attribute, user device 210may group songs by artists whose name falls into two letter intervals(e.g., may group artists whose names start with A and B, such as AC/DC,Aerosmith, Beastie Boys, the Beatles, etc.; may group artists whosenames start with C and D, such as Coldplay, Creedence ClearwaterRevival, Dave Matthews Band, DMX, etc.).

When the attribute is voice frequency, the granularity may specify afrequency range. For example, when a user selects a frequency range of100 Hertz, user device 210 may group songs with a voice frequency thatfalls into 100 Hertz intervals (e.g., between 1000 Hertz and 1100 Hertz,between 1100 Hertz and 1200 Hertz, etc.).

When the attribute is a song rating, the granularity may specify arating range. For example, when a user selects a rating range of two,user device 210 may group songs with a rating between one and two, arating between three and four, etc. In some implementations, the usermay specify a quantity of rating categories, and user device 210 mayseparate the songs into the rating categories based on a user rating.

When the attribute is a quantity of times that the song has been played,the granularity may specify a quantity range. For example, when a userselects a quantity range of ten, user device 210 may group songs thathave been played between 1 and 10 times, between 10 and 20 times, etc.In some implementations, the user may specify a quantity of categoriesfor the number of times played, and user device 210 may separate thesongs into the categories based on the quantity of times that each songhas been played.

When the attribute is a geographic region, the granularity may specify asize of the geographic region. For example, a user may specify to groupsongs by city, country, continent, hemisphere, etc.

In some implementations, user device 210 may receive the attributesand/or granularities from a data structure (e.g., stored locally on userdevice 210 or obtained from another device over a network, such asserver device 220). Additionally, or alternatively, user device 210 mayanalyze media files to determine the attributes (e.g., beats per minute,voice frequency, etc.) and/or granularities (e.g., based on the entirerange of attribute values associated with a particular attribute).Additionally, or alternatively, user device 210 may obtain theattributes from metadata associated with the media files. Additionally,or alternatively, a user may input, to user device 210, the attributesand/or granularities associated with the media files.

Returning to FIG. 4, process 400 may include presenting therepresentation of the media files on a grid based on the first attributeand the second attribute (block 430). In some implementations, userdevice 210 may present (e.g., display) a representation of a song on atwo-dimensional grid on a user interface of user device 210. Eachposition on the grid may represent one or more songs with particularattribute values. For example, a particular vertical position on thegrid (e.g., a row) may represent songs with a tempo that falls within aparticular range (e.g., 140 bpm to 160 bpm). As another example, aparticular horizontal position on the grid (e.g., a column) mayrepresent songs of a particular genre (e.g., classical, dance, etc.).Thus, each cell (e.g., combination of vertical position and horizontalposition, or row and column) in the grid may represent a song or groupof songs having two particular attribute values (e.g., classical songswith a tempo of 140-160 bpm).

Each cell may represent a single song, a group of songs (e.g., in thescenario where multiple songs meet the attribute values specified by thecell position), or no songs (e.g., in the scenario where no songs meetthe attribute values specified by the cell position). A cell may berepresented by a square, a rectangle, a point where a row meets acolumn, an icon, a color, an image, etc. In some implementations, a cellmay be represented by an image that conveys additional information aboutthe song or songs represented by the cell, such as an image associatedwith an attribute of the songs represented by the cell (e.g., an imagethat represents a particular genre of music, a flag of a country wherethe song originated, etc.) and/or an image associated with an attributeof a portion of the songs represented by the cell (e.g., an image of anartist that sings some, all, or a majority of the songs represented bythe cell). In some implementations, a cell that is frequently selectedby a user (e.g., greater than a threshold quantity of times and/or moreoften than other cells) may be represented in a different manner thanother cells (e.g., highlighted, presented in a different color, etc.).

In some implementations, the media files may be arranged in anothershape other than a grid, so long as the media files are presented inrelation to one another, based on the attributes. For example, ratherthan each cell being square or rectangular in shape, each cell may be adot, a circle, a diamond, an oval, a heart, a different color, etc. Insome implementations, the cells of the grid may not be visible, anddifferent positions on a user interface and/or display may be associatedwith different cells and/or songs. For example, the grid may be hiddenunder an image, such as a rainbow with dark colors in one corner andlight colors in the opposite, diagonal corner. Additionally, oralternatively, the grid may be arranged along two dimensions other thana vertical dimension and a horizontal dimension (e.g., two diagonaldimensions forming an X). In some implementations, the grid may berepresented by a transition in color from one cell to another. Forexample, each column (or row) of cells may be presented in a differentcolor (e.g., a different red, green, and blue color combination toproduce any color capable of being displayed on user device 210), andeach row (or column) of cells may be presented as a different shade(e.g., lighter or darker) of that color.

As further shown in FIG. 4, process 400 may include receiving a userselection of a portion of the grid corresponding to one or more mediafiles (block 440). In some implementations, user device 210 may receivea user selection of a portion of the grid, such as one or more cells ofthe grid. For example, a user may select one or more cells by clickingon the cells (e.g., using a mouse or another input device), by clickingand dragging across multiple cells, by touching a screen location atwhich the cells are displayed and/or presented (e.g., using a finger ora pointer on a touch screen), by swiping across multiple cells displayedand/or presented on the screen (e.g., on a touch screen), etc.

In some implementations, information associated with the selected songsmay be presented on the screen as a user selects the songs. For example,user device 210 may present one or more attributes of the selectedsongs. Additionally, or alternatively, user device 210 may present aquantity of selected songs, a combined length of the selected songs(e.g., a sum of the lengths of each selected song), an attributeassociated with a majority of the selected songs, etc.

Process 400 may also include creating a playlist, based on the userselection, that includes the one or more media files (block 450). Forexample, user device 210 may receive the user selection of one or moresongs, and may create a playlist that includes the songs. In someimplementations, the songs may be placed in order in the playlist basedon the order in which the songs were selected by the user. For example,the user may select a first cell before selecting a second cell (e.g.,may swipe across a first cell and then a second cell). User device 210may order the songs in the playlist by placing the songs represented bythe first cell before the songs represented by the second cell.Additionally, or alternatively, a user may specify that the songs are tobe played in a random order, and user device 210 may randomize the orderof the songs in the playlist.

In some implementations, a cell may represent more than one song. Forexample, the first cell may represent 3 songs and the second cell mayrepresent 4 songs. In this scenario, user device 210 may randomly orderthe 3 songs represented by the first cell in slots 1-3 of the playlist,and may randomly order the 4 songs represented by the second cell inslots 4-7 of the playlist. By placing songs in this order, user device210 ensures that each song represented by the first cell is placed inorder in the playlist before each song represented by the second cell.

Alternatively, user device 210 may place the songs represented by eachcell in order based on a trend associated with the user selection. Forexample, the user may select a first cell that represents 2 songs beforeselecting a second cell that represents 2 different songs. The firstcell may represent songs with a tempo between 120-140 bpm, and thesecond cell may represents songs with a faster tempo, between 140-160bpm. User device 210 may determine a trend based on the order of userselection. For example, user device 210 may determine that the user hasselected songs in order of increasing tempo (e.g., from 120-140 bpm to140-160 bpm). Based on the trend, user device 210 may order the songs inthe playlist in order of increasing tempo. For example, the 2 songsrepresented by the first cell may have a tempo of 125 bpm and 130 bpm,and the 2 songs represented by the second cell may have a tempo of 140bpm and 155 bpm. Based on the determined trend of increasing tempo, userdevice 210 may place the 125 bpm song first, the 130 bpm song second,the 140 bpm song third, and the 155 bpm song fourth. In a scenario wheretwo or more songs have the same tempo (or other attribute), user device210 may randomly order those songs in the playlist.

As shown in FIG. 4, process 400 may include playing the playlist (block460). In some implementations, after user device 210 has created theplaylist, the playlist may be automatically played without receivingadditional input from a user. Alternatively, user device 210 may createthe playlist, and may play the playlist based on receiving user input toplay the playlist.

While a series of blocks has been described with regard to FIG. 4, theblocks and/or the order of the blocks may be modified in someimplementations. Additionally, or alternatively, non-dependent blocksmay be performed in parallel.

FIG. 5 is a diagram of an example implementation 500 relating to process400 shown in FIG. 4. FIG. 5 depicts a user interface 510 that may bepresented on user device 210. A user may interact with user interface510 to specify attributes that determine how media files (e.g., songs)are to be represented on a display of user device 210, such as byspecifying attributes to associate with a vertical axis and a horizontalaxis (520), a granularity for the attributes (530), and particularattribute values and an order in which to present the attribute valuesalong the axes (540).

As shown by reference number 520, a user may select a first attribute ofa song to be represented along a first dimension (e.g., a verticalaxis), and a second attribute of a song to be represented along a seconddimension (e.g., a horizontal axis). For example, the user may selecttempo to be presented along a vertical axis, and may select genre to bepresented along a horizontal axis. In some implementations, userinterface 510 may prevent a user from selecting the same attribute formore than one axis. As shown by reference number 530, the user may alsoselect a granularity for the attributes, such as 10 bpm for the tempoattribute and 1 genre for the genre attribute. As shown by referencenumber 540, a user may select particular attribute values and/or anorder in which to present the particular attribute values on a userinterface, such as classical, pop, rock, and dance genres. The attributevalues may include the set of values, for a particular attribute, thatcan be associated with a song.

As shown by reference number 550, the user may provide input (via aninput element, such as a button, a menu item, etc.) to user interface510 that saves the selected attributes and granularities, and that usesthe selected attributes and granularities to represent media files whena playlist creator application is launched. In some implementations,selection of the input element may cause the playlist creatorapplication to be launched.

FIG. 6 is a diagram of an example implementation 600 relating to process400 shown in FIG. 4. FIG. 6 depicts a user interface 610 that may bepresented on user device 210, and which may be used to select mediafiles to play and/or add to a playlist.

As shown in FIG. 6, user interface 610 may present a two-dimensionalgrid of rows and columns that create cells. In some implementations, therows and columns may be presented horizontally and vertically. In otherimplementations, the rows and columns may be oriented in another manner(e.g., diagonally in a diamond shape). Each cell may represent one ormore songs associated with a first attribute value and a secondattribute value.

In example implementation 600, the cells may be arranged on the gridbased on the genre of the songs that the cells represent. For example,each column of cells may represent songs classified in a particulargenre or group of genres. A user may input (e.g., via user interface510) the genres to be presented and the order in which the genres are tobe presented (e.g., from left to right, top to bottom, etc.) on userinterface 610. As shown in FIG. 6, the user may select a set ofattributes separate from or including genre to present on user interface610, such as a tempo of a song (e.g., a bpm speed), a release date of asong, a musical instrument type used in a song, a voice type of thevocals for the song, etc.

In example implementation 600, the cells may also be arranged on thegrid based on the tempo (e.g., in beats per minute) of the songs thatthe cells represent. For example, cells representing songs with a slowtempo (e.g., 10 or fewer bpm) may be represented toward the bottom ofuser interface 610 and/or the grid, and cells representing songs with afast tempo (e.g., 140 or more bpm) may be represented toward the top ofuser interface 610 and/or the grid.

The granularity input by the user may determine the difference in tempobetween songs represented in adjacent rows. For example, the user mayinput a granularity of 10 bpm. Based on this input granularity, userinterface 610 may present cells representing songs with a tempo of 10 orfewer bpm in a bottom row, cells representing songs with a tempo of11-20 bpm in a second row (e.g., second from the bottom and immediatelyabove and adjacent to the bottom row), cells representing songs with atempo of 21-30 bpm in a third row (e.g., third from the bottom andimmediately above and adjacent to the second row), etc. Cells that arealigned in the same row may represent songs with the same or a similartempo.

In some implementations, user interface 610 may present cells based on adefault granularity. For example, user device 210 may use a defaultgranularity when a user does not input a granularity or when auser-input granularity results in too few or too many rows/columns(e.g., less than or greater than a threshold). In some implementations,user device 210 may determine the default granularity based on a rangeof attribute values and a quantity of cells that fit within userinterface 610 (e.g., on the grid). For example, the songs in a user'slibrary (e.g., stored on user device 210 or accessible by user device210 via a network, such as from server device 220) may range in tempofrom 10 bpm to 140 bpm. User device 210 may determine that userinterface 610 is capable of presenting 20 rows of cells, and may evenlydivide the attribute value range (10 bpm through 140 bpm) into the 20rows. For example, user device 210 may determine the quantity ofattribute values and/or the difference between the highest and lowestvalue in the range (here, 140−10=130), and may divide that quantity(130) by the quantity of cells (20) to determine an interval value forthe default granularity (6.5). Each row may represent songs with a tempothat falls within an interval determined by the interval value. Forexample, the bottom row may represent songs with a tempo between 10 bpmand 16.5 bpm, the second row may represent songs with a tempo between16.5 bpm and 23 bpm, etc. Either of the values on each end of theinterval may be inclusive or exclusive.

Similarly, user device 210 may determine a default granularity bydetermining the total quantity of attribute values and dividing by thequantity of cells capable of being presented on user interface 610. Forexample, the songs in a user's library may be classified into 40 genres,and user interface 210 may be capable of presenting 20 columns of cells.User device 210 may divide the quantity of attribute values (40 genres)by the quantity of cells (20 cells) to determine the interval value forthe default granularity (2 genres). Based on the default granularity,each column of cells on user interface 610 represents 2 genres of songs.

User device 210 may determine the quantity of cells that fit on userinterface 610 based on a cell size. In some implementations, the cellsize may be selected by a user. Additionally, or alternatively, thecells may have a minimum size and/or a maximum size. For example, theminimum and/or maximum cell size may be based on a display resolution ofuser device 210, a type of user device 210, an input method (e.g., touchscreen or mouse pointer) for user device 210, a screen or display sizeof user device 210, a size of user interface 610, or other displaycharacteristics of user device 210 and/or user interface 610.

Additionally, or alternatively, user device 210 may determine thequantity of cells that fit on user interface 610 based on a userinterface size. In some implementations, user interface 610 may be thesame size as a display of user device 210 (e.g., may take up the entiredisplay). Alternatively, user interface 610 may be smaller than thedisplay of user device 210 (e.g., may take up a portion of the display).User interface 610 may be resized, which may cause user device 210 toadjust the cell size, the quantity of cells that fit on user interface610, and/or the granularity. In some implementations, user interface 610may be larger than the display of user device 210, and may require theuser to scroll to access different portions of user interface 610, asdiscussed herein in connection with FIG. 7.

FIG. 7 is a diagram of an example implementation 700 relating to process400 shown in FIG. 4. FIG. 7 depicts user interface 610 presented on userdevice 210.

As shown in FIG. 7, user interface 610 may be larger than the display ofuser device 210, and may require the user to scroll to access differentportions of user interface 610. For example, the songs in a user'slibrary may be classified into a quantity of genres larger than aquantity of columns (or rows) of cells that can fit on user interface610. In this implementation, the user may scroll (e.g., left and right,up and down, etc.) to access different portions of user interface 610.

User device 210 may detect a different type of user input used forscrolling through user interface 610 than used for selecting cells thatrepresent songs to be added to a playlist. For example, a user may swipe(e.g., without first touching and holding or touching and waiting forfeedback) across the screen of user device 210 to scroll across userinterface 610. Alternatively, this input method may be used to selectsongs.

Additionally, or alternatively, the user may touch and hold (e.g.,maintain contact) with the screen of user device 210 before swiping inorder to select songs to be added to a playlist. In someimplementations, user device 210 may provide feedback to the user thatindicates that a swipe will select songs rather than scroll. Forexample, the user may touch and hold, and the screen of user device 210may flash, change color, display a prompt, etc. to indicate that a swipewill select songs. Additionally, or alternatively, user device 210 mayemit a sound (e.g., a buzz, a beep, etc.), may vibrate, etc. to indicatethat swipe will select songs. Alternatively, this input mechanism may beused to scroll across user interface 610. In some implementations, userinterface 610 may scroll, as a user is selecting songs, when an inputmechanism (e.g., a finger, a cursor, etc.) approaches an edge of userinterface 610.

In some implementations, a user may zoom in or zoom out on userinterface 610 (e.g., using an input mechanism such as a mouse, a finger,etc.). When the user zooms in on a group of cells, each cell in thegroup may increase in cell size. This may allow user interface 610 topresent additional information associated with the songs represented byeach cell (e.g., images and/or text that identify song names, artists,albums, etc., associated with the songs).

Additionally, or alternatively, zooming in on a group of cells maydecrease the granularity of the attribute value interval. For example,user interface 610 may arrange cells by tempo according to a granularityof 20 bpm, and each cell may represent songs with a tempo that fallswithin a 20 bpm interval. A user may zoom in on two cells that representthe interval from 100-120 bpm and 120-140 bpm, respectively. Based onzooming in, user device 210 may change the granularity of each cell sothat each cell represents songs with a tempo that falls within a 5 bpminterval (e.g., 100-105 bpm, 105-110 bpm, 115-120 bpm, 120-125 bpm,125-130 bpm, 130-135 bpm, and 135-140 bpm). User device 210 may adjustthe granularity so that the cells fit within user interface 610. In someimplementations, user device 210 may allow a user to continue to zoom inuntil each cell represents a single song. User device 210 may performsimilar but opposite operations when a user zooms out of user interface610.

In some implementations, user interface 610 may provide a mechanism(e.g., a button, a menu item, etc.) for a user to access user interface510, or another similar user interface, to change preferences such asattributes, granularity, the presented attribute values, the order ofthe presented attribute values, etc.

FIG. 8 is a diagram of an example implementation 800 relating to process400 shown in FIG. 4. FIG. 8 depicts user interfaces 810 and 820 that maybe presented on user device 210. In some implementations, userinterfaces 810 and 820 may correspond to and/or provide similarfunctionality as user interface 610.

User interface 810 shows an example of four songs, each with a differenttempo, represented by cells on user interface 810. The songs with aslower tempo are represented by cells on one end of the grid (e.g., thebottom), and the songs with a faster tempo are represented by cells onthe other end of the grid (e.g., the top). The songs may each berepresented by a different cell, or multiple songs may be groupedtogether to be represented by the same cell, depending on thegranularity. The songs may be in the same genre, and may be representedin the same column.

User interface 820 shows an example of arranging cells based on arelease date of songs represented by the cells. For example, each columnof cells may represent songs released in a particular year or span ofyears (or a particular month, span of months, week, span of weeks, day,span of days, etc.). A user may input (e.g., via user interface 510) therelease date values to be presented and the order in which the releasedate values are presented (e.g., from left to right, top to bottom,etc.) on user interface 610. In some implementations, the release datesmay be presented chronologically (e.g., from left to right, as shown).Alternatively, a user may specify a different order for the releasedates to be presented, and/or may choose release dates to include orexclude from the user interface.

FIG. 9 is a diagram of an example implementation 900 relating to process400 shown in FIG. 4. FIG. 9 depicts a user interface 910 that may bepresented on user device 210. A user may use an input mechanism 920 tointeract with user interface 910, which may present a selected cellindicator 930 and/or selected song information 940. In someimplementations, user interface 910 may correspond to and/or providesimilar functionality as user interface 610.

As shown in FIG. 9, a user may interact with user interface 910 using aninput mechanism 920. In some implementations, input mechanism 920 mayinclude a mouse and/or a cursor controlled by the mouse. Additionally,or alternatively, input mechanism 920 may include a mechanism tointeract with a touch screen, such as a finger, a stylus, a pointer,etc. Functions described herein as being performed by swiping using atouch screen may also be performed by clicking and dragging using amouse. Additionally, functions described herein as being performed bytouching and holding before swiping (or other similar language) may alsobe performed by clicking and holding before dragging.

A user may select one or more cells on a grid presented by userinterface 910. For example, a user may use their finger to swipe apattern on a touch screen device, as illustrated by selected cellindicator 930. In some implementations, the user may swipe to selectcells, or may touch and hold before swiping to select cells, asdescribed herein in connection with FIG. 7. Additionally, oralternatively, a user may select individual cells one at a time.

Additionally, or alternatively, a user may use multiple swipes (oranother input mechanism) to select multiple portions of the grid thatare not adjacent to one another (e.g., that cannot be selected using asingle swipe). In this scenario, user interface 910 may provide amechanism for a user to indicate when the user has finished selectingsongs using multiple swipes. For example, a user may swipe three times,and may hold a finger on the screen at the end of the last swipe, whichmay indicate that the user has finished selecting songs.

User interface 910 may present selected cell indicator 930 thatindicates cells that the user has selected via input mechanism 920. Forexample, selected cell indicator 930 may present selected cells in adifferent manner than non-selected cells, such as by highlightingselected cells, presenting selected cells in a different color,outlining selected cells, changing an image presented on the selectedcells, etc.

Selected cell indicator 930 may include a swipe pattern that coverscells that have been selected by the user. In some implementations, theuser selection may include a portion of a cell. In this scenario, userdevice 210 may add all of the songs in the selected cell (e.g., the cellto which the selected portion belongs) to the playlist. Alternatively,user device 210 may determine a position of the selected portion inrelation to the entire cell, and may add songs to the playlist based onthe position of the selected portion. For example, if a cell representsthree songs with a tempo of 100 bpm, 110 bpm, and 120 bpm, and the userselects the top third of the cell, user device 210 may only add the 120bpm song to the playlist.

Selected song information 940 may present information associated withthe selected songs. In some implementations, the information may bepresented when a user indicates that the user has finished selectingsongs (e.g., stops swiping, touching, dragging, etc.). Additionally, oralternatively, the information may be presented as a user selects thesongs, and may be updated as new songs are selected. The presentedinformation may identify one or more attributes of the selected songs,such as a quantity of selected songs, a combined length of the selectedsongs, etc.

User device 210 may receive an indication that a user has finishedselecting songs. In some implementations, a user may swipe to selectsongs, and may hold their finger on the touch screen at the end of theswipe, which may indicate that the user has finished selecting songs.Additionally, or alternatively, user device 210 may prompt the user(e.g., when a user holds at the end of a swipe, when the user stopstouching the touch screen, etc.), and may receive a response to theprompt to determine that the user has finished selecting songs. In someimplementations, when a user selects one or more cells, user device 210may present a list of songs represented by the selected cells, and maypermit the user to play all of the listed songs or select one or moresongs for playback.

In some implementations, a user may select songs to be played and/oradded to a playlist using a first swipe, and may indicate the length ofthe playlist using a second swipe. For example, after user device 210receives an indication that a user has finished selecting songs, userdevice 210 may prompt the user to indicate a length for the playlist.The user may use an input mechanism (e.g., a keyboard, a mouse, etc.) toindicate the length of the playlist. Additionally, or alternatively, theuser may swipe on the screen of user device 210, with the length of theswipe representing the length of the playlist (e.g., a shorter swipeindicates a short playlist and a longer swipe indicates a longerplaylist). User device 210 may randomly select a subset of the selectedsongs to be included in the playlist, based on the indicated length.

As an example, if a user would like to play slow tempo classical music,the user may select one or more cells from the bottom left portion ofuser interface 910. As another example, assume that a user wants to playmusic during a workout. The user may wish to start the workout withmedium tempo classical songs that gradually increase in tempo andtransition into fast tempo dance songs, and may wish to finish theworkout with medium tempo dance songs. In order to create a playlistthat meets these criteria, the user may swipe the pattern shown byselected cell indicator 930.

As another example, a user may swipe upward and then downward in asingle column of user interface 910, which may cause user device 210 toplay music of a single genre (e.g., classical music) that increases intempo and then decreases in tempo. If the same cell is selected twice(e.g., once on the swipe up and once on the swipe down), user device 210may divide the songs represented by the cell so that some of the songsare played in the first part of the playlist (e.g., as the tempo isincreasing) and other ones of the songs are played in the second part ofthe playlist (e.g. as the tempo is decreasing). Similarly, a user mayswipe left or right in a single row, which may cause user device 210 toplay music of multiple genres that have a similar tempo (e.g., within agranularity interval, such as 20 bpm).

FIG. 10 is a diagram of an example implementation 1000 relating to theprocess shown in FIG. 4. FIG. 10 depicts user interface 910 (FIG. 9),and user interfaces 1010 and 1020 that may be used to create and/or playa playlist 1030.

As shown in FIG. 10, a user may select songs to include in a playlistvia user interface 910, and may provide an indication that the user hasfinished selecting songs. Based on the indication, user device 210 maypresent user interface 1010 that presents the created playlist 1030.User interface 1010 may present information associated with playlist1030. For example, user device 210 may create a name for playlist 1030(e.g., “Dance: 15 songs”) based on one or more attributes of theselected songs. The name may be based on an attribute associated with amajority of the selected songs (e.g., the majority of the songs may beclassified into the dance genre) and/or associated with all of theselected songs (e.g., a quantity of selected songs). Additionally, oralternatively, user interface 1010 may present a representation of thecells that were selected to create playlist 1030 (as illustrated by theshaded rectangles to the left of the playlist name, “Dance”). In someimplementations, user device 210 may store the created playlist 1030 sothat the user does not have to select the songs again in the future.

The user may select playlist 1030, which may cause user device 210 topresent the songs included in playlist 1030 and/or to play playlist1030, as illustrated by user interface 1020. In some implementations,user device 210 may play playlist 1030 upon receiving an indication thatthe user has finished selecting songs (e.g., without requiring furtherselection of playlist 1030 via user interface 1010).

Implementations described herein simplify the playlist creation processby allowing a user to create a playlist by selecting a representation ofa song or a group of songs presented on a two-dimensional grid thatcategorizes songs based on two or more attributes.

While certain implementations are described herein in connection withthe attributes of tempo and genre, the described functions may besimilarly implemented using any of the attributes described herein.Furthermore, while certain implementations are described herein inconnection with songs, the described functions may be similarlyimplemented for audio other than songs, for video, and/or for othermedia content.
